VAGINAL SYRINGE.

SPECIFICATION forming part of Letters Patent No. 677,091, dated June 25, 1901.

Application led January 9, 1901. Serial No. 42,625. (No model.)

To all whom, t pray concern.'

Be it known that we, HAETLAND LAW and HERBERT E. LAW, citizens of the United States,residingat San Francisco,in the county of San Francisco, State of California, have invented certain new and useful Improvements in Vaginal Syringes, of which the following is aspeciiication, reference being had therein to the accompanying drawings.

This invention relates to vaginal syringes, and particularly to that class embodying refluent connections by which the wash is inj ected and ejected through the syringe-nozzle.

The invention has for an object to provide an improved construction of shield adapted to forma plug or tampon for the part to be washed and to effecta water-tight connection which will permit the desired movement of the nozzle without escape of liquid or inconvenience to lthe patient.

A further Objectis to provide this plug with air-inlet means to prevent the formation of a vacuum within the vagina or other part being treated by reason of vthe reiiuent action of the syringe.

A further important object of the invention is to provide a nozzle or pipe adapted for connection with either a bulb, a recurrentpipe, or a fountain-syringe having a return discharge.

Another object of the invention is to improve the discharge means for this nozzle and also the connecting-pipe for use with a fountain-syringe.

Other and further objects of the invention willhereinafter appear in the following specication, and the novel features thereof will be pointed out in the appended claims.

In the drawings, Figure 1 is aperspective of theinvention having a bulb applied thereto. Fig. 2 is a central vertical section showing the application of the inlet and discharge pipes from a fountain-syringe. Fig. 3 is a vertical section of the shield with parts broken away. Fig. 4 is an elevation of the connecting-pipe for a fountain-syringe, and Fig. 5 is a detail vertical section taken at right angles to the section shown in Fig. 2.

Like letters of reference refer to like parts in the several gures of the drawings.

The shieldAis formed of any suitable flexible materialsuch, for instance, as rubberand is provided at its enlarged end with a stiffened edge A. The opposite end of the shield is provided with a neck A2, adapted to closely lit the exterior wall of the nozzle B. This shield is substantially oval in shape and formedat the lower posterior end with a raised portion A3, the object being to fit the shield to the shape of the body and the vaginal oriiice into which the nozzle of the syringe is inserted. The stiffened edge A may be made solid, Fig. 2, or effected in any desired manner--for instance, by introducing therein a coiled spring A4-which renders the edge iiexible and permits movement of the nozzle without interfering Withthe connection of the shield. Y

In the ordinary syringe, Where the shield or plug makes a watertight closure with the vaginal orifice, the escaping Water by the return-pipe produces a throbbing very unpleasant for the patient and causes nervousness. Furthermore, when a bulb-syringe is used and the Water is drawnvback into Ythe bulb the suction thereby produced is very great and pullsthe delicate organs out of position, thus causing permanent injury. To overcome this objection, the shield has been provided with an air-inlet provided with suitable means to prevent the V discharge of liquid through the inlet. As illustratingone form of such inlet, we have shown an inlet-tube A5, which extends from the interior of the shield to the exterior thereof. This tube may be held open in any desired manner-for instance, `by a coiled spring As--and may be provided with any desired means for preventing the escape of liquid therethrough. The discharge end of this tube is shown in Fig. l as provided with a slit A7 in its body, at the discharge end thereof, which permits the entrance of air and prevents the escape of liquid. If desired, any preferred form of valve may be placed in the tube-for instance, as

.shown at A8, in Figs. 2 and 3.

The nozzle .or pipe B is provided with a tubular extension B' and at its opposite end with inj ector-j ets B2 and a central dischargechannel B3, both of which communicate with said extension. The nozzle is also provided with a discharge-aperture B4, disposed at a point back from its end, so as to drain all liquid possible adjacent to the shield. When IOC the nozzle is used in connection with a bulb, as shown in Fig. l, the bulb may be applied to the lower threaded end of the extension B. In this form or method of application the injected and ejected liquid may pass through the same channel.

XVhen the nozzle is used in connection with the inlet-tube C and discharge-tube C2 used in connection with a fountain syringe, a connecting-pipe D is applied by means of a collar D, engaging the threaded end of the extension B and provided with inlet and discharge nipples D2, having independent channels, as shown in Fig. 2. The opposite end of this pipe D is provided with a shoulder D3 and a plugging-sleeve D4 beyond the same. Discharge-openingsD5 extend through the ange D6, formed at one side of the shoulder D3,aud communicate with the central discharge-passage within the pipe. The space between the exterior of the pipe D and the extension B communicates with the inletnipple and constitutes a feed-passage. This passage is closed at one end by the contact of the flange DG with the wall of the nozzle B; but suitable injector-channels D7 are formed through the flange D, so as to comm unicate with the injector-openings B2,wl1ich are disposed in aliuement with the space beyond the shoulder D3, so as to secure an even distribution of liquidto the several openings. The plugging end B4 of the pipe makes close contact with the wall B5 at the end of the nozzle, thus preventing any communication be` tween theinlet and discharge channel. Vhen the nozzle is thus used, the liquid is injected only through the openings B2, and the ejection is solely through the central passage of the pipe D.

The operation and function of the flexible shield is to form a plug or tampon, so that liquid injected into the vagina may be held there at the will of the user, and also to allow the use of a syringe in a sitting or reclining position without wetting the clothing or couch. The thickened edge of the shield holds the same in proper shape to fit the body, and the flexible properties of the shield permit it to be adapted to any variation in the shape or form of the orifice into which it is introduced and also permits the nozzle to be moved into any desired position for washing the parts. An important feature of this shield is the air-inlet into the vagina while the water is being withdrawn therefrom, which prevents all suction or bubbling and the consequent unpleasantness and injury to the patient. The admittance of air allows the Vagina to be entirely drained, which cannot be accomplished if a vacuum forms therein, as from one to three ounces will be retained inthe body, according to the size of pipe used. It will also be noted that the objectionable suction heretofore experienced in the use of bulb-syringes is entirely obviated by the use of the present form of shield. The form of nozzle is also especially important in this art,

as it permits the use of either a bulb or fountain syringe bythe application of the simple attachment for the connection of the inlet and discharge tubes. The use of the dischargeejectors from the nozzle communicating with the central passage at a point below the injection-jets permits the complete draining of liquid from the vagina, while the tubular extension of the nozzle forms a convenient means of attachment for the cooperative devices. For this reason the invention contemplates the manufacture of the nozzle or the shield independent 'of the other parts, although in their cooperative relation very eicient results are attained.

It will be obvious that changes may be made in the details of construction and configuration of the several parts without departing from the spirit of the invention as defined by the appended claims.
